Prep the wings: Pat the chicken wings completely dry with paper towels.
The drier they are, the crispier they get.
Season: In a large bowl, toss the wings with baking powder or cornstarch, salt, pepper, paprika, and oil. Coat evenly but lightly—no clumps.
Arrange for crisping: Place wings on a wire rack set over a foil-lined baking sheet. Leave space between pieces so air can circulate.
Roast: Bake at 425°F (220°C) for 40–45 minutes, flipping halfway.
Wings should be golden and crisp. For extra crunch, broil for 2–3 minutes at the end, watching closely.
Make the sauce: In a saucepan over medium heat, melt the butter. Add garlic and cook 30–60 seconds until fragrant, not browned.
Stir in honey, soy sauce, vinegar, sesame oil, and red pepper flakes.
Thicken (optional): If you want a stickier glaze, whisk cornstarch with water and stir into the sauce. Simmer 1–2 minutes until glossy and slightly thick.
Glaze the wings: Transfer hot wings to a large bowl. Pour over the sauce and toss until every piece is coated and shiny.
Finish and serve: Sprinkle with sesame seeds and green onions.
Serve immediately while crisp and sticky.
